Abstract We have synthesized a new tetranuclear manganese cluster with a distorted cubane-like [Mn4O4]-core. High field magnetization experiments reveal an intramolecular antiferromagnetic coupling between the four manganese ions. We explain our results both qualitatively and quantitatively by a simple spin square model in terms of four equal antiferromagnetic exchange interactions in the core with coupling strengths of J = -1.69 K.
